Benefits of technology

The present invention provides a serial fan structure that has improved anti-vibration effects and reduced assembling costs and defects. The male connector has a certain degree of elasticity which allows it to engage with the female connector to provide the serial fan with the anti-vibration effect without the need for additional elements between the first and second assembling sides. The fully assembled serial fan of the present invention has these advantages.

Problems solved by technology

On the other hand, these electronic products also generate more and more heat during operation thereof.
Since the high amount of heat produced during operation would adversely affect the reliability and the service life of the electronic products, it has become an important issue as how to remove the produced heat from the electronic products.
However, it is possible one single fan does not provide sufficient air flow to ensure good heat dissipation effect of the electronic product.
The serial fan operating at the increased rotating speed will vibrate and produce noise due to a resonant effect between the serially connected fan frames.
This condition will cause reduced stability of the electronic product.
The additional vibration-absorbing member 12 would increase the assembling cost of the serial fan and tends to cause defects of the serial fan when being poorly assembled to the two fans 10, 11.
In brief, the prior art serial fan with additional vibration-absorbing member has the following disadvantages: (1) requiring increased assembling cost; and (2) tending to have defects due to poorly assembled vibration-absorbing member.

third embodiment

[0046]When the first and the second frame 20, 21 in the third embodiment are assembled to each other, the serial fan structure 2 can equally have good anti-vibration effect, lowered assembling cost, and minimized defects in assembling.

[0047]Please refer to FIG. 5A that is an exploded perspective view of a serial fan structure 2 according to a fourth embodiment of the present invention. As shown, the fourth embodiment is generally structurally similar to the first embodiment, except that three male connectors 24 are provided on the first assembling side 201 of the first frame 20 while three female connectors 25 are provided on the second assembling side 210 of the second frame 21. In the fourth embodiment, the three male connectors 24 and the three female connectors 25 are separately arranged in the vicinity of any three corners of the first assembling side 201 and the second assembling side 210, respectively.

fourth embodiment

[0048]When the first frame 20 and the second frame 21 are assembled to each other, the mounting posts 23 on the first assembling side 201 are inserted into the mounting holes 22 on the second assembling side 210, and the male connectors 24 are correspondingly engaged with the female connectors 25, so that the first and the second frame 20, 21 are serially connected to form the serial fan structure 2. Through the engagement of the elastic male connectors 24 with the female connectors 25, the fully assembled serial fan structure 2 in the fourth embodiment can equally have good anti-vibration effect without the need of providing additional cushioning or vibration-absorbing elements between the first and the second frame 20, 21, and accordingly has lowered assembling cost and minimized defects in assembling.

[0049]FIG. 5B shows a variant of the fourth embodiment. The major difference between the variant and the fourth embodiment is that, in the variant, the first assembling side 201 is p...

fifth embodiment

[0051]When the first frame 20 and the second frame 21 are assembled to each other, the mounting posts 23 on the first assembling side 201 are inserted into the mounting holes 22 on the second assembling side 210, and the male connectors 24 are correspondingly engaged with the female connectors 25, so that the first and the second frame 20, 21 are serially connected to form the serial fan structure 2. Through the engagement of the elastic male connectors 24 with the female connectors 25, the fully assembled serial fan structure 2 in the fifth embodiment can equally have good anti-vibration effect without the need of providing additional cushioning or vibration-absorbing elements between the first and the second frame 20, 21, and accordingly has lowered assembling cost and minimized defects in assembling.

[0052]FIG. 6B shows a variant of the fifth embodiment. The major difference between the variant and the fifth embodiment is that, in the variant, the first assembling side 201 is prov...

Abstract

An anti-vibration serial fan structure includes a first frame having a first assembling side and a second frame having a second assembling for connecting to the first assembling side. The first assembling side is provided with at least one mounting post or mounting hole and at least one male or female connector. The second assembling side is correspondingly provided with at least one mounting hole or mounting post and at least one female or male connector. The male connector has a certain degree of elasticity, so that the engaged male and female connectors provide a vibration-absorbing effect to save additional cushioning elements, enabling the serial fan structure to have lowered assembling cost and minimized defects in assembling.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a serial fan structure, and more particularly to an anti-vibration serial fan structure that includes a plurality of fan frames axially serially connected to one another through engagement of at least one elastic male connector with at least one female connector separately correspondingly provided on two adjacent fan frames, so that the serial fan provides anti-vibration effect without the need of additional cushioning or vibration-absorbing elements to thereby save assembling cost and minimize assembling defects.BACKGROUND OF THE INVENTION[0002]Due to the quick progress and development in the information technological field, the currently available electronic products all are designed to have high performance, high frequency, high operating speed, and minimized weight, thickness and volume. On the other hand, these electronic products also generate more and more heat during operation thereof. Since the high amount of heat...
